dcloud插件市场中是有现成的组件的：

[steps步骤条插件地址：https://ext.dcloud.net.cn/plugin?id=34][steps_https_ext.dcloud.net.cn_plugin_id_34]

# 使用方法 #

### script中引入 ###

import uniSteps from '@/components/uni-steps/uni-steps.vue'
    export default { 
        components: { uniSteps}
    }

### template中使用 ###

<uni-steps :options="[{title: '事件一'}, {title: '事件二'}, {title: '事件三'}, {title: '事件四'}]" :active="1"></uni-steps>

针对组件有部分改动，效果图如下：

组件的使用如下：

import uniSteps from '@/components/uni-steps/uni-steps.vue'
    export default { 
       components: { uniSteps},
    	data(){ 
    		return{ 
    			activeIndex:-1,
    			stepOptions:[
    				{ title: '基本信息',index:0}, 
    				{ title: '门店信息',index:1}, 
    				{ title: '门店图片',index:2}, 
    				{ title: '等待审核',index:3}
    			],
    		}
    	},
    	methods:{ 
    		selectStep(item){ 
    			console.log(item);
    		}
    	}
